1746-OBP16產(chǎn)品特點(diǎn)

遠(yuǎn)程液位監(jiān)控系統(tǒng)結(jié)構(gòu)

　　本文設(shè)計(jì)的遠(yuǎn)程液位監(jiān)控系統(tǒng)結(jié)構(gòu)如圖1所示：其中，處理器芯片采用ARM微處理器S3C44B0X；S3C44B0X自帶8路10位ADC進(jìn)行A/D轉(zhuǎn)換來采集液位數(shù)據(jù)，通過擴(kuò)展DAC0832實(shí)現(xiàn)D/A轉(zhuǎn)換以輸出控制量；S3C44B0X連接10M以太網(wǎng)卡RTL8019AS，提供網(wǎng)絡(luò)功能的硬件接口；μC/OS-Ⅱ移植到S3C44B0X上，提供操作系統(tǒng)的支持，方便了應(yīng)用程序的開發(fā)和對(duì)整個(gè)系統(tǒng)的管理；嵌入式TCP/IP協(xié)議棧LwIP移植到μC/OS-Ⅱ平臺(tái)上，實(shí)現(xiàn)對(duì)網(wǎng)絡(luò)數(shù)據(jù)的軟件處理，從而為嵌入式系統(tǒng)提供網(wǎng)絡(luò)通信功能；遠(yuǎn)程PC機(jī)客戶端登錄到嵌入式系統(tǒng)服務(wù)器上，通過以太網(wǎng)實(shí)現(xiàn)兩端數(shù)據(jù)的實(shí)時(shí)交互。
